Jaw crusher is comm known as jaw crusher, also known as Laohukou. The crushing chamber is composed of two jaw plates, a movable jaw and a static jaw, which simulates the movement of the animal's jaws to the material crushing operation. It is widely used in the crushing of various ores and bulk materials in mining and smelting, building materials, highways, railways, water conservancy and chemical industries. The dyeing high compressive strength of the crushed material is 320Mpa.     When the jaw crusher is working, the movable jaw plate cyclically reciprocates against the fixed jaw plate, sometimes approaching and sometimes leaving. When approaching, the material is crushed by squeezing, splitting, and impact between the two jaws; when leaving, the crushed material is discharged from the discharge port by gravity.
    In the process of crushing huge rocks into small rocks, the * crusher is usually the main crusher. The history is long, and the strong crusher is the jaw crusher. When feeding the jaw crusher, the material is poured into the crushing chamber containing the jaw teeth from the entrance, and the jaw teeth push the material against the chamber wall with huge force, breaking it into smaller stones. Supporting the movement of the jaw teeth is an eccentric shaft, and this eccentric shaft penetrates the frame of the fuselage. Eccentric motion is usually produced by flywheels fixed at both ends of the shaft. Spherical roller bearings are often used in flywheels and eccentric support bearings. The bearings withstand huge impact loads, abrasive sewage and high temperatures.
